IX RESEARCH       


(a)        Completed


(i)        Investigation of Human Immunodeficiency Virus Type-I infection among children in southwest Nigeria Nov, 2000 to Nov 2002.


(ii)        Incidence and burden of Hepatitis C virus infection among selected occupational groups in a semi-urban centre in southwest Nigeria.


(iii)       Pattern of Hepatitis B Virus Serological Markers in Asymptomatic Residents of Awuda Community in Nnobi, southeastern Nigeria.


(iv)      Hepatitis B virus infection Among Sexually Active Individuals in Nigeriasubmitted to carried out from April 2015 to August, 2016.


(v)        Hepatitis B virus infection among asymptomatic residents of low income community in Ibadan, southwest Nigeria.


(vi)       Evaluation of performance testing of different rapid diagnostic kits in comparison with EIAs to validate detection of Hepatitis B virus among high risk group in Nigeria carried out from April 2010 to July, 2011.


 (b)       In Progress


(i)         This study aims to investigate HBV, HCV, HDV and HIV monoinfection and co-morbidities among selected population groups in southwestern Nigeria. This study is ongoing for sample collection and some serological components have yielded two publications while the molecular analysis is yet to be concluded.


(ii)        Epidemiology and molecular characterization of some viruses implicated in maternal and infant morbidity in southwest Nigeria: It is hoped to attract a support for the concluding part of the study. This is also an ongoing research and it is at the preliminary stage in which we are investigating Hepatitis viruses (HAV, Rubella etc) of public health importance among selected population in southwest Nigeria.


(iii)          This study targets the detection and genotyping of Hepatitis E Virus in Pigs and human in southwestern Nigeria with a view at investigating the roles of this pathogen in infertility, economic loss in animals and the implication of public health importance.


(iv)         Surveillance and Monitoring and Molecular Characterization of Filoviruses (Ebola, Maburg), Arenavirus (Lassa) and other Haemorrhagic viruses in Southwestern Nigeriaaims at providing epidemiological data on the current circulation of these pathogens and advise the health stakeholders on possible control measures and strategies. Two papershave been published on Ebola and Lassa from this study while the molecular component of the work is still ongoing.


(v)        Pattern of serological markers of Hepatitis B virus among pregnant women in Ibadan, southwest Nigeria: This study was also carried out to investigate HBV markers (HBsAg/Ab, HBcAb, HBeAg/Ab and HBVDNA) of infection among pregnant women attending ante-natal clinic at the University College Hospital Ibadan in order to look at the possibility of vertical transmission of HBV from mother to child and also to guide against early infection which result in chronicity due to long period of the circulation of the virus in the unborn child from birth till grown up stages. Similar studies have also been conducted among the general population in Ibadan.


(vi)         Multiple testing of Pathogens to support the elimination of Malaria Parasites in Nigeria in collaboration with DrAbd El Waheed of the Division of Microbiology and Animal Hygiene, Department of Animal Sciences, Goerttigen, Germany (AVH Foundation Fellowship). This research is still ongoing, having concluded the training components of the work for capacity development. A paper has been published from this grant and the next phase of the study is ongoing.


(vii)        Detection and Molecular Characterization of Enteroviruses and Coxsakieviruses among school children in southwest Nigeria in collaboration with Department of Microbiology, FUNAAB. A postgraduate dissertation has been written and defended by a student from this research. Further investigations into the molecular characterization of the pathogens including the expansion of the work are ongoing.


(viii)       This study is investigating the Epidemiology and Molecular Characterization of HDV among HBV monoinfected and HIV comorbidity in Abuja Nigeria in collaboration with Department of Medical Laboratory Sciences, UNN, Nsukka. A PhD student is benefitting from this research with sample collection and laboratory analysis reaching the peak.


(ix)         Molecular Epidemiology of Hepatitis D virus among HBsAg Carriers in Selected Health Facilities in Nigeria. This is a collaborative work between three institutions and a research laboratory in France which covers the southwest, Northeast and the southeastern Nigeria. The proposal for this study has been submitted to the UI/UCH IRB for approval. The preliminary parts of the study are ongoing.


(x)          Investigation of pathogens implications in diarrhea among HIV positive patents attending ARV clinics in some selected healthcare facilities in southwest Nigeria. This is a collaborative work between IAMRAT and the Department of Microbiology, University of Ibadan/Federal University of Agriculture, Abeokuta. The approval of the proposal for this study has been obtained from the UI/UCH IRB and the study has since commenced.


(xi)       Investigation of Mother-to-child transmission of HIV in pregnancy and among HIV-exposed infants accessing care at a PMTCT clinic in southwest Nigeria. This is a follow-up ongoing study carried out in Ibadan in selected PMTCT clinics among HIV positive pregnant women in order to proffer appropriate intervention.

1.   Human Immunodeficiency Virus Type-I infection among children in Southwestern Nigeria: (MSc Virology project).


2.   Incidence of Hepatitis C Virus infection in a semi-urban community of southwestern Nigeria: (PhD degree Virology thesis).
